Vice President Joe Biden first ran for president in the 1980s. He tried again in 2008 before becoming President Obama's running mate. At a weekend inaugural event, Biden declared, "I'm proud to be president of the United States." His son politely corrected him. One persistent question is whether Biden may try one more run in 2016.

Morning Edition has a team of reporters spread out across the city, getting a feel for how things are going in different areas. Thousands of people are descending on the nation's capital to be a part of President Obama's second inauguration.

As feared, the reports from Algeria about the number of people killed during last week's hostage crisis at a gas plant are getting grimmer.

Super Bowl XLVII will be a never-before matchup of teams coached by two brothers.

The Baltimore Ravens, led by John Harbaugh, will play his younger brother Jim's San Francisco 49ers on Feb. 3 in New Orleans.

Maybe it should be called the Harbowl, as they're saying on NFL.com.

Good morning.

Though he and the vice president have already taken their oaths of office, President Obama is due this noon to stand outside the Capitol for his ceremonial swearing in and then to deliver his second inaugural address.

We'll start live blogging later this morning, so check back if you want to follow along. The highlights should include:

The widow of a slain Mississippi civil rights leader Medgar Evars will help open the inaugural ceremony Monday. President Obama has selected activist Myrlie Evers-Williams to deliver the invocation. She's the first woman and lay person to have the honor.

Both India and the U.S. seem disappointed with each other after the high expectations raised by President Obama's election in 2007. India is concerned about the uncertainty in U.S. policy toward China and Afghanistan.

The casualties are still being counted from last week's attack on an Algerian gas plant by Islamist militants. The four-day siege left dozens of people dead. The group warned of more such attacks against any country backing France's military intervention in neighboring Mali. For a perspective on Mali, Renee Montagne talks to Vickie Huddleston, who served as the U.S. ambassador to Mali from 2002 to 2005.

After the four-day hostage crisis in Algeria, the death toll has risen to at least 81. Algerian forces that were searching the natural gas plant in the Sahara that was taken over by Islamist militants found at least 25 more bodies on Sunday.
